Situated in an active tectonic region, Santiago de Chile, the country's capital with more than
six million inhabitants, faces tremendous earthquake risk. Macroseismic data for the 1985 …

The fundamental period of vibration is a key parameter for the spectral approach to seismic
design of structures, as it significantly affects the evaluation of the response spectra values …

During a three year-period, the participants of a NATO Science for Peace project performed
ambient noise measurements inside buildings in four European countries. This paper …

Since the early nineteen seventies we have been measuring the in-situ dynamic
characteristics of the different structures built in Portugal, essentially based on ambient …

This paper estimates fundamental translational period and dam** ratio parameters and
examines the changes in dynamic characteristics of a set of low-to-medium rise buildings in …

Minarets are very slender structures with an old existence. The historical ones are made of
cut‐stone‐block masonry assembled in peripheral cylindrical wall with an interior helicoidal …

Fundamental period of vibration, dependent on mass and stiffness structure characteristics,
is a key parameter in assessing seismic demand. The period can be evaluated both by …

The importance of designing safe and economic structures in seismically active areas is of
great importance. Thus, develo** tools that would help in accurately predicting the …

In the aftermath of recent earthquakes there has been substantial field evidence
demonstrating that the collapse of several existing structures was caused by the effects of …

The characterization and monitoring of buildings is an issue that has attracted the interest of
many sectors over the last two decades. With the increasing use of permanent, continuous …
